| 摘 要： | 根据1983年5月、9月和10月的胶州湾水域调查资料,分析了有机农药六六六(HCH)在胶州湾水域的分布、来源和季节变化。研究结果表明:在胶州湾水域没有受到HCH的污染。通过河流输入近岸水域和通过地表径流直接输入近岸水域的HCH含量是一样的,非常低。HCH来源是面来源。在夏季,输入的胶州湾水域的HCH含量与春、秋季相比,相对较高。根据HCH在胶州湾水域的分布、来源和季节变化,认为1983年HCH含量变化由胶州湾附近盆地的雨量大小所决定。在胶州湾湾口水域,表层的HCH水平分布状况与底层的HCH水平分布状况一致。HCH的含量在表层的减少完全依赖胶州湾潮流的稀释,不仅在水体表层中HCH含量会形成低值区域,而且在水体底层中HCH含量也会形成低值区域。 |

| Abstract: | Based on the data from the investigations in the Jiaozhou Bay in May,September,and October in 1983,the organic pesticide HCH content distribution,source,and seasonal variation are analyzed.It is learnt from the results that no HCH pollution can be concluded.The HCH contents in the coastal waters into which the rivers flow are the same low as those in the coastal waters into which the surface runoffs flow.HCH comes from the areal source.HCH carried into the Jiaozhou Bay has its higher content in summer than that in spring or autumn.It is learnt from the HCH distribution,source,and seasonal variation that the HCH variation in 1983 depends upon the rain fall variation in the valleys around the Jiaozhou Bay.In the open water of the mouth into the bay,the HCH content distribution in the bottom waters is the same as that in the surface waters.The surface HCH dilution can be attributed to the tidal currents in the Jiaozhou Bay.Due to the tidal currents,lower HCH content appears not only in the surface layer but also in the bottom layer. |
